'1 b M whom. it may canoe/Eli;

lie it known that Ll'lannr Etienne Ham nnUN, a citizen of the United States, residing at Dubois, in the county of Clearlield and Eltate of Pennsylvania, have invented certain new and useful 1111])1'0YQll'lGllilS in Rat- Traps, of which the following is a specifi CMJIODU This lnventlon relates to new anduseful improvements in rat traps and theprincipal object of the inventlon isito provlde a device of this character which will catch and retain the rat and which will be self setting.

Another object of the invention is to so arrange the bait that after once being placed it will remain in position as the rats are unable to reach it.

A further object of the invention is to provide a trap door with means associated therewith which will prevent the door from 0 ening until the rat is in the center thereo so as to avoid a premature opening of the door and thus scare the rat.

Another object of the invention is to provide adevice of this character, which is simple and durable in construction, rellable and efficient in operation and one which can be manufactured and placed upon the market at a minimum cost.

The invention also consists in certain other features of construction and in the combi nation and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings, wherein. like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a sectional view through a trap.

Fig. 2 is a section on line 2-2 of Fig. 1.

In these figures 1 indicates a receptacle, preferably made in circular form. This receptacle is provided with a top 2 inclined downwardly toward the center where it is provided with an opening 3. 4 indicates a trap door normally closing this opening and hinged to the top at 5. This door is held shut by means of the weight 6 secured to the lever 7 secured to the door at 8. A stop lever 9 pivoted to the top at 10 engages the lever 7 to prevent upward movement of this weighted lever, and thus hold the door locked, and this lever is held in engaging.

position.byf. .means of alcatch l1 pivoted thereto near its lower end andengagmg a slioulder12 on the lever 7 thus holding the leveragalnst movement. The lever? 1s provided with; a bent. down end 13 to whichlis pivoted a link 14 which has'one endpivoted to the catch 11 and its otherend pivoted to the stemlh of a small platform 16 located inthe center ofthe door, the steinpassing through a hole in the door. A bait carrying :rod 17 1s reinovably sccured'in a lug .18

formed on the side of the receptacle and this rod has its upper endcurved so as to bring the .bait directly above the platform 16, the

]god carrying a pointed pin 19 to receive the ait.

With the door closed and the trap set the platform 16 is located above the door, and when a rat, attracted by the bait, walks down the inclined top on to the door the said door is prevented from being opened by reason of i the fact that the parts are held in locked position by means of the links and catch. As the rat discovers that the bait is above him he will climb on the platform 16 to reach the bait and his weight will cause said platform to lower and thus lower the end of the link 14 and cause its other end to rise, thus moving the catch 11 upwardly out of engagement with the shoulder 12. As the weight of the door 1 and the rat is heavier than the weight 6, the door will swing downwardly,

thus causing the weighted end 6 of the lever.

7 to swing upwardly. Since the stop lever 9 is inclined with relation to the lever 7 it will swing upwardly with the lever 7 to permit the door 4 to swing downwardly to cast the rat into the receptacle. As soon as the rat leaves the door 4:, the weight 6 will cause said door to close and the catch 11 will engage the shoulder 12 and thus lock the parts in closed position in readiness to entrap another rat.

It is thought from the foregoing that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make slight changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

I claim as my invention:

1. The combination with a swinging door, of a vertically movable platform, a weighted lever normally retaining said door in a closed position, a stop lever engaging said loi A i i i i i a and n a isaldi l ed l ve s a catch pivoted/co said stop lever and engaggconigl of H ll patent; may be ottainecl for V p wp mn p ,1n.c.'"

weighted lever, locking means for retainin said stop lever in engagement with said weighted lever, and means connected 'to said platform and to said locking means to operate said lockin means. 2. In a trap, the combination with a swinging door, of a vertically movable platform, a weighted lever normally retaining said door in a closed position, a shoulder on said lover, a stop lever pivotally connected t0 the a ing said shoulder and a link having one end pivoted to said platform and another end pivoted to said catch for operating the catch when the platform moves downwardly.

3QA trap comprising a trap door, a weightedleve'r connected with said trap door, a

stop lever pivoted to the trap and beingindined with relation to the w'eightedlever whereby the of said stop lever may slide upon the weighted lever, a catch pivoted to said stop lever and engaging the weighted U lever, a platfor nfipositione'd above said door,

and means connecting the platform to the catch for permitting the door to swing when the platform moves downwardly.

4. A rat trap comprising a trap idoor,'a' weighted lever connected with the trap door, a secondleverpivoted to the trap, means for looking said lever to the weighted stop lever, a member movably arranged in the trap door and a pivoted linkconnecting said member to the said lockmg means forreleasing the same when a rat gets on said movable member. a
